  • Inter-liner for a safety helmet and method of assembly
    Patent number: 4114197
    Abstract: A substantially rigid dome-shaped shell encloses a deformable cap-like headpiece of uniform thickness. The headpiece conforms to the contour of the wearer's head and cooperates with the shell to define a dome-shaped cavity which is sealed around its bottom portion. The cavity is filled with an expandable plastics foam material which hardens and conforms to the contour of the headpiece. In one embodiment, spacer members are positioned within the cavity and extend from the headpiece to the shell for positioning the shell relative to the headpiece, and in another embodiment, the shell is spaced within a slightly larger outer shell by resilient energy-absorbing foam pads. In a further embodiment, separate earpiece units are contour fitted to the wearer's head with a resilient expandable plastics foam material, and a modified helmet shell is used as a holder for fitting the headpiece and earpiece units.

  • Safety helmet with individualized head-contoured inter-liner
    Patent number: 4044399
    Abstract: A substantially rigid dome-shaped shell encloses a deformable cap-like headpiece of uniform thickness. The headpiece conforms to the contour of the wearer's head and cooperates with the shell to define a dome-shaped cavity which is sealed around its bottom portion. The cavity is filled with an expandable plastics foam material which conforms to the contour of the headpiece. In one embodiment, spacer members are positioned within the cavity and extend from the headpiece to the shell for positioning the shell relative to the headpiece. In another embodiment, the shell assembly is spaced within a slightly larger outer shell by resilient energy-absorbing foam pads to form an inter-liner, and the headpiece is formed by stretching a piece of leather with a device having a predetermined contour. In another embodiment, edge roll strip assemblies are attached to the lower edges of the outer shell and provide for removing and interchanging the inter-liner.
